Research Abstract:
Single walled carbon nanotubes and their more economical counterparts, carbon nanofibers, are promising components of nanocomposite systems with significant improvements predicted for tensile strength, strength to weight ratio and processing ability compared to conventional materials. To synthesize such nanocomposites, the carbon nanotubes need to be dispersed well enough to avoid inter-bundle load transfer. They also need to be functionalzed to secure the nanotubes to the matrix. However this functionalization cannot introduce defects at a level that disrupts or compromises the integrity of the nanotubes. These efforts have been hampered by the practical constraint that current methods to measure matrix dispersion and the degree of functionalization are extremely time consuming or not accurately known at all. The problem addressed in this project is the development of reliable, reproducible and efficient spectroscopic methods for determining two important system properties: nanotube dispersion and aggregation state in the matrix, and degree of chemical functionalization on the nanotube sidewall.  less info
